The BEEP component sends some "stupid beep" to the speaker of the client. The "beep" is triggered by a corresponding Trigger-property on server side.

There is an other component #{SOUND} - which is the one to be used for playing sound files. The BEEP component uses the output of the ASCII beep character, which is also available on e.g. industry terminals without sound processor, or uses the default toolkit's beep processing.
